污染气体SO_2和NO_2紫外和可见光谱吸收截面测量

SO_2 and NO_2 Absorption Cross Section Measurements in Ultraviolet and Visible

本文用我们自己研制的光谱测量系统测量了常温下的ＳＯ２在２５０～３３０ｎｍ波段和ＮＯ２在 ２８０～６００ｎｍ波段的吸收截面，波长分辨率优于０．１ｎｍ．该测量结果可适用于传统低光谱分辨率仪器遥感大 气污染气体含量，也可为激光差分吸收测量或激光雷达测量污染气体含量提供参考．

The absorption cross section of the gases of SO2 and NO2 are measured under ambient temperature within the wavelength range of 250-330 um and 280-600 um respectively. The optical resolution is better than 0.1 um. The results are applicable to traditional low-resolution system for remote sensing the atmospheric pollution gases, and are also useful to DIAL.
